Altoids Sour Chewing Gum

Purchased at Wal*Mart when we went looking for the mobiBLU, which they didn't have in their brick'n'mortar store in Mountain View. Instead I got a tiny skateboard (it's slightly over a foot long) for $4.88 and some Altoids Sour Chewing Gum. Concerning the latter:

Good:

• Cool box -- little metal boxes are neat
  
• Very, very sour...
  

Bad:

• ...for about three chews. No tootsie-pop jokes, please.
  

These things have huge amounts of sourness stored up, but they release it all in one go.
